Using tretinoin has been a significant step in managing my acne and perioral dermatitis. From personal experience, sticking to a consistent skincare routine is crucial when using tretinoin due to its potency and potential to irritate sensitive skin. Starting slow is key – I began applying tretinoin every other night and gradually increased as my skin adapted. This helped minimize redness and peeling, common side effects during the first weeks. Moisturization should not be overlooked. I found that applying a gentle, fragrance-free moisturizer after tretinoin helped reduce dryness and discomfort. Also, sunscreen is a must every day, as tretinoin makes skin more sensitive to UV rays. Tracking progress through before and after photos kept me motivated. Seeing the improvement over time, especially in reducing acne and calming perioral dermatitis, confirmed the effectiveness of this treatment. Remember, everyone's skin is different, so it’s important to consult with a dermatologist before starting tretinoin. Patience and consistent care make all the difference in achieving healthy, clearer skin.
